IMPROVEMENT IN SCREEN WlNDOW-BLlN DS.

Specification forming part of Letters Patent No. l 57,194, datedNovember 24, 1874 5 application filed October 31, 1874.

To all whom it may concern:

Be it known that I, J OHN P. CLARK, J r., of Jackson, Jackson county,Michigan, have invented a new and Improved Window, Screen, and Blind, ofwhich the following is a specification:

In the drawing, Figure 1 represents a front elevation of my improvedcombined window, screen, and blind. Fig. 2 is a vertical trans versesection of the same, and Fig. 3 is a top View of the interior frame.

Similar letters of reference indicate corresponding parts.

The object of my invention is to so improve that class of windows thatturn on side hinges in the window-casing that the blinds are arranged inadjustable connection therewith, together with detachable panes andscreens, furnishing thereby better ventilation and greater conveniencein use.

My invention consists of a hinged windowframe havlng an interior bottomhinged part, which may be partially-opened, and which is arranged with ablind in connection with a detachable top piece and sliding pane andscreen.

In the drawing, A represents the outer window-frame, which is hinged tothe side of the window-easing in the usual manner, to be thrown open andclosed entirely, if desired. The outer frame A incloses an inner frame,B, that fits closely into the open part of frame A, being hinged alongthe lower edge to the same, so that it may be swung into inclinedposition as far as two pivoted and slotted side strips,

U, near the upper end, will admit of. The sliding strips 0 settle inside recesses b of the frame A, when the inner frame is carried backinto the outer frame, frame B being secured in this position by suitablesliding or springlatch pirces d. The blind-slats D are pivoted in theusual manner to the interior frame B, at the inside thereof, andadjusted at any angle of inclination by the blind-slat rod D. The toppiece B of frame B is detachable, being connected by dovetails to frameB or hinged at one side, to be thrown open when frame B is placed ininclined position, so that the glass pane E and wire screen F, whichslide in inner guide-grooves e of frame B, may be taken out and replacedas desired. i

In hot weather the screen would be used and the pane taken out, whileduring the cold season the pane is reinserted and the screw taken out.

The window would thus furnish a summer protection against mosquitoes,flies, 850., while giving the proper ventilation, either by open ing thewindow completely for a time, or by placing the inner frame in inclinedposition.

A suitable weather-strip of the outer frame extending along the innerframe, together with an outer bottom flange of the lower piece of theinner frame, secure the tight closing of the frames against wind, dust,and rain, and form a very useful and convenient window for buildings ofall kinds.

As the glass pane may be too large for easily handling the same, it maybe divided into two or more parts and separated by grooved lateralstrips connected to sliding side strips. The panes are in this mannerreplaced with less expense in case of breakage.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent l. The combined window, screen, and blind, composed ofside-hinged outer window-frame A and bottom-hinged interior frame B,having blinds D D, detachable top piece B, sliding pane E, and screen F,arranged and applied, substantially as specified.

2. The hinged interior pane and screen holding frame B, provided withadjustable blindslats D, as described.

3. The interior frame B, having side grooves e, in connection withsliding pane E and screen F, and detachable binding top piece B,substantially as specified.
